Abstract Objective To explore the feasibility of CT on multiple plane reconstruction of the lesion 5th lumber nerve at the same slice, providing the basis for the clinical diagnosis of L₅ neuropathy. Methods 30 patients with of L₅ neuropathy and 20 normal adults were scanned by GE Light Speed 16 and PHILIPS iCT 256-slice CT, reconstructed with their own workstations (GE, ADW4.1 and Philips Brilliance 3.0) to observe the normal anatomy and basic disease of L₅ nerve. Results 20 cases (40 sides)of normal L₅ nerve were symmetrically displayed from starting point to margin of psoas major and 15 cases (75%) to upper sacroiliac joint in oblique coronal plane. 20 cases (100%)of L₅ nerve were displayed from starting to sacroiliac joint plane and 6 cases (30%) were shown to sacral plexus or upper sciatic nerve by internally rotating oblique coronal plane. In all of the L₅ neuropathy, there were travel direction and tension status change in 16 cases(24 sides), shrink in 12 cases(18 sides), localized thickening 3 cases(5 sides), fuzzy 15 cases(18 sides) and distorted in 1 case(1 side). L₅ neuropathy involved L₅-S₁ disc lateral protrusion with bone hyperplasia (10 cases), hypertrophy of transverse process of 5th lumbar vertebra (5 cases), L₅ spondylolysis (8 cases), L5 vertebral compression fracture (3 cases) and pelvic malignancies(4 cases). Conclusions HRCT multiple plane reconstruction technique at the same slice can provide a valuable diagnosis basis for L₅ neuropathy.
